Abstract:
Random survey was conducted during course of investigation in 2016-17 in different tribal districts of the state viz., Anuppur, Dindori, Mandla, Shahdol and Umaria demonstrated that root-knot nematode is of widesoccurrence. The most common species Meloidogyne graminicola was found associated with rice - wheat cropping system and related weeds, in different localities. All these localities were found infested with root knot nematode, (M. graminicola). The plant infected with M. graminicola were found devitalized, stunted with yellow leaves. The root system of such plants had severe galling with poorly developed roots. The soil samples were collected from the infested fields and the samples were analysed using Baermann’s funnel technique followed by Cobb sieving and decanting methods. The soil population of M. graminicola was found associated with rice-wheat cropping system and total population of the nematode ranged from 180 to 390 nematodes (J2) per 200 cm2 soil. The soil sample collected from rice – wheat areas of Anuppur (10), Dindori (5), Mandla (2), Shahdol (8) and Umaria (24) encountered M. graminicola. The maximum (390 N) and minimum (130 N) population densities of M. graminicola was recorded in Badwar and Raipur village of Umaria district respectively.
